Abstract
A semiconductor light emitting device includes a substrate, a plurality of light emitting cells, a connection part, and a concavo-convex part. The light emitting cells are arrayed on the top surface of the substrate. Each of the light emitting cells has a first-conductivity-type semiconductor layer, an active layer, and a second-conductivity-type semiconductor layer that are sequentially stacked on the top surface of the substrate. The connection part is formed to connect the light emitting cells in series, parallel or series-parallel. The concavo-convex part is formed in at least one of the bottom surface of the substrate and the top surface of an isolation region between the light emitting cells.
